Couplers And Optocouplers Employ Tension Clamp Design

Tension clamp relay couplers and optocouplers in 6-mm wide housings join firm's DIN-rail mounted family of terminal blocks. The blocks provide three clear, internal cross-connection options for looping power supplies and reference potentials that are safe from finger-touch hazard. The pluggable cross-connections come in 2- to 10-pole versions. Tension clamps require no special wire preparation. The installer strips the wire, opens the tension clamp, inserts the wire, and releases the clamp. The cross-connection jumpers need no special tools or additional terminals.
